|
how do you determine the central atom?
|
farthest and lowest to the left/ lowest electronegativity
|
|
|
what element never receives lone pairs?
|
hydrogen
|
|
|
what do you do after counting the number of total valence electrons?
|
split in half for bonding pairs
|
|
|
what does VSEPR stand for?
|
Valence Shell Electron Pair Revulsion
|
|
|
what is the VSEPR theory?
|
electrons will repel each other and the molecular shape will be the result of minimizing that repulsion.
|
|
|
what is the Expanded Oclet?
|
the option of when the central atom is of the 3rd period or later than if necessary they can take more than 8 electrons in a lewis structure.
|
|
|
what is Electron pair Geometry?
|
the shape of the molecule based on the number of total pairs of electrons on the central atom.
|
|
|
what is molecular shape?
|
the shape of the molecules based on the number of atoms bonded off the central atom
|
|
|
what are electron geometry and molecular shape based off of?
|
VSEPR theory
|
|
|
what is bond character?
|
bond character is whether the molecule is pure covalent, polar covalent, or ionic. this is determined by finding the differences in electronegativity.
|
|
|
what is polarity?
|
when the areas in the molecule have higher concentrations in one area than another.
